NCT ID NCT07684716
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This trial tests whether a personalized non-drug regimen—including diet changes, walking, and sugar-free gum—can improve bowel preparation quality for colonoscopy. Participants are adults scheduled for a colonoscopy. The goal is to see if this tailored approach leads to better colon cleaning and higher detection of polyps or cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- individualized non-pharmacological regimen (diet, exercise, education, sugar-free gum)
- What this could lead to
- If effective, this approach could improve colonoscopy quality and cancer detection rates without relying on higher laxative doses.
- What could go wrong
- This is a single-center trial with 339 participants, so results may not apply broadly. The intervention is complex and adherence may vary.
